3rd display: laptop and 2 displays

Solution 1:

Get a UGA external video card, it turns your USB 2.0/3.0 port to hdmi or dvi or vga port which u can use to connect your 3rd monitor. You will need to install drivers come with the uga card. It's a cheap solution to multiple monitors. You can connect up to 6 monitors with UGA cards. Each UGA card only cost $50.

My setup: one monitor connected to VGA port on my laptop,2nd monitor connected to hdmi port on my laptop,(my laptop has both VGA and hdmi port), the 3rd monitor connected to USB through a external UGA card)

Solution 2:

According to the HD Graphics 4000 triple monitor support page,

In most cases, three independent displays are supported in the following configurations:

• If two of the displays are DisplayPort monitors
• If one of the displays is an Intel® Wireless Display (Intel® WiDi)
• If the built-in display is an Embedded DisplayPort (eDP)

Since you don't have any DisplayPort outputs on your machine, the setup you want only works if your internal monitor is connected via eDP, not LVDS.

To check if your computer's built-in display uses an embedded DisplayPort (eDP) or LVDS connector type: From the Windows desktop, press Ctrl+Alt+F12 key combination. If prompted select Advanced Mode application mode. Select Options and Support, change System Information to Built-in Display. Check the Connector Type field.

If it turns out to be LVDS, this setup is unfortunately not compatible with your hardware.

Note that, as far as I know, the vast majority of current laptops don't use eDP as it's a new standard (except some 3D laptops), so it generally isn't possible to run 3 monitors off an HD 4000 GPU unless your laptop has DisplayPort. (Or if you run one monitor off WiDi.)
